I have done some redesign on my DIY Turntable and have changed the platter material to Delrin, and the drive system to an AC motor and drive controller. This allows me to put up my Mark Kelly controller for sale. I built it but never got around to testing it. It is one of my nicer builds. It comes with a separate battery box and the umbilical l cord between the two. I am selling it for $175 which is alot less than I build it for. Have a look at some pictures.
